Resolve-url-loader doesn't appear to make any change to compiled CSS

[jasonlav]

extract-text-webpack-plugin: ^3.0.0
node-sass: ^4.5.3
sass-loader: ^6.0.6
webpack: ^3.5.1
resolve-url-loader: ^2.1.0

app.css appears to remain unchanged regardless of implementation of resolve-url-loader.

At first glance... The way you are using extract text you are moving the CSS after the bundle is generated. This makes the url paths wrong. I have never successfully changed structure like this, not for want of trying. I had to settle for a flat structure. (My experience was webpack 1 though.)

Solution is unrelated to resolve-url-loader. See the publicPath option on the ExtractTextPlugin. It is also recommended to use the include option as well.
